摘要：

Analytical results are obtained for the amplitude of a spherical wave backscattered from a solid cylinder immersed in water. The effects of transducer directivity and transmitted pulse duration are included. Backscatter measurements for comparison with theory are made using straight stainless steel wires ranging from 0.13 to 0.26 mm diameter, and acoustic transceivers operating at 1, 2.25, and 5 MHz. The results are used to evaluate the use of thin wires as standard targets.
